Specification forming part of Lettersif-Patcnt No. 4824633 dated June 27, 1865.

To all 'whom 'it may concern'.- 1 y I Beit known that I, WILLIAM TosHA.cn,'of the city, county, and State of New York, have invented anew and useful Improvement in Window-Fasteners@ and I do hereby declare the following tohea full, clear, and exact dey scription thereof, reference being had to the `accompanying drawings, which form a part of All travelers upon railway-cars have experi-V enced the difficulty often attendent upon the uufastening of the ordinary catches in coinmon use ou car-windows and the annoyance 'resulting therefrom,-while the railway companies have on their part felt the disadvantages of suchcatches in the frequent breakage of the windows and fastenings consequent upon theirirnpertections. Attemptshavebeenmade vto overcome-these objections by the: use of split'or divided knobs whose divisions are f hinged together, so as to form levers to (lisengage the catches; but iu all suoli which have come under my observation the' levers form- I'ing the knob traversed in a horizontal plane, so that .the act of lifting the window by means of the knob would not operate to disengage the fasteniu gs, a pinching pressure the-reonin a horizontal plane being necessary. To this movement (in itselfvery awkward) the fingers of weak persons are often unequal, and there are other evident objections to the device.

It is the objectof my invention to overcome these diiiiculties and to so-arrangc the win- The knob by which the window is to be lifted, although made in the usual convenient form exterior, is yet divided into two pieces, a and b, of which one,.b, is rigidly securedto the windowsash'in thecenter thereof, andthe other,

a, is hinged to the iirst upon its upper rear edge so as to close down neatly thereon, andl thus completethe knob.

From the .inner edge ofy Lhehinged piece a of the knob an arm, a', projects inwardly through a perforation in the sash so as to eni gage with a slot cut inA one arm, c, of an'anguiar lever, A, pivoted on the opposite side thereof or within arecess cut therein t'o receive it. The other arm, d, of this lever A is connected by a rod or wire, e, with the free end of a'spriug-catch, B, secured upon the side edge of the'sash, and which locks in the usual manner into a suitable recess in the windowframe. The arm c of the lever A is thrown up by the movement of the 'hinged piece a of the window-knob, and the pressure naturally and necessarily exerted upon this knob to raise the.

window is thus conveniently made to release it fr om its fastening by withdrawing the catch B. This catch B may be of any convenientforui, that represented in Figs..1 to 4 of the drawings being simply a straight metallic spring, whose lower and free end is so bent as to form the catch. Figs. 5 and 6 illustrate a catch, made of asiinple hook, pivoted at its up per end, and pressed against the window-frame by a separate spring, K. Other forms will readily snggest themselves, and all varieties ot' springs may be applied in this connection.

I contemplatirusiug my invention in combination with double catches placed on both sides ofthe sash, operatiu g both by the saine lever and knob. Y

Having now4 fully described my invention, what I claim therein as new, and desire to se cure by Letters Patent, is-

The arrangement in or upon awindow-sash, in combination therewith and with. the arms c and d of an angular lever, A, of a spring-actuated windowcatch, B, and -a hinged'dever and windo\v knob a b, as described, in such a manner as that pressure exerted upon the knob to raise the sash will also diseugage its fasten ings, all substantially in the manner herein set forth.

`The foregoing specication of my improvement in spring-catches for wiudow-sashes signed by me this 28th day of March, A. D. 1865.
